DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Retry for auto-mode classifier calls that come back unavailable

Not switched on
Useful2 Signal3
Models

Auto mode's model-picking call can retry when unavailable, but the retry count defaults to zero.

Exponential-backoff retries for the auto-mode classifier exist but the remote-config retry count defaults to 0.

What

Auto mode's model-choosing request can now be retried when it fails as unavailable, with exponential backoff starting at 2 seconds, capped at 10 seconds, plus 25% jitter. The retry count comes from remote config, is clamped to 0 through 10, and defaults to 0, so with no server value set the loop never runs and behaviour is unchanged.
